You get my PM from tuesday??
Woot mine is getting closer. Sorry about the shipping requiring a signature but those tards will leave anything sitting on a porch step to get stolen. And I wanted the best shipping available to cover both of us.

The porting, in fact, does change the inside diameter of the TB by opening it up to a full 75mm throughout. From the factory, the castings have a huge lip that shrinks down the I.D., along with several bumps, stops, burs, etc that can be smoothed out. It's a proven fact that a correctly ported TB increases HP/TQ, and been a proven fact on the LS1 engine for oh say about....10 yrs now. Both with dyno's and track results.
I also wouldn't have done 100+ of these things by now, with over 100+ happy customers if it didn't work.

I knew it would bump up the inside, just curious as to how much. 50 bucks for a 75mm beats spending a **** ton on a BBK 80MM that won't work my CAI, lol. Too bad I don't have the money for the 92/92.
